The cable for the cable reel may be of any well known type and either asingle wire cable or a double wire cable, as may be desired.

In Fig. .4; of the drawings for the purpose of illustration, ll haveindicated a double wire cable 17 the reel end of which extends throughthe periphery or drum of the reel and into the interior thereof, and isthere separated, and one conductor 17 is led off in one directionthrough a passageway 8 through the, reel shaft 8 and is grounded to thelocomotive frame in any desired man- 'ner, and the other conductor 17 isled of" in the opposite direction through the said passageway 8 and isconnected to acollector ring 18 which is insulated from the drum. Thiscollector ring may be of any desired type and it is electricallyconnected with the driving motor or motors on the car in any suitablemanner.

20 indicates as an entirety a spooling device for spooling the cableupon the reel. It may be of any suitable construction and should beadapted for spooling the cable whether bepaid off from the reel end orthe operators end of the locomotive. T have illustrated this spoolingdevice conven tionally as comprising a double threaded shaft 20 carryingtraveler 2b, which The parts return has secured to it a frame in whichis mounted guide rollers 20 for the cable. This double threaded shaft ismounted at either end in bearing plates or arms 21 which, mounted on thereel shaft 8 so as to be swung about the axis of the said shaft.

21, 21 are arms or brackets secured at the sides of the bearingstandards 9 and 9 respectively, and adapted, one pair to engage andsupport the double threaded shaft at one side of the reel, and the otherpair to engage and support the said shaft on the other side of the reel.22 is a sprocketwheel rigidly secured to the said double threaded shaftat one end, and connected by a'chain 22 with a sprocket wheel on thereel shaft 8.

When the cable is to be paid 05 from the operator s end of thelocomotive it is desirable to have it guided therefrom by some suitabledevice, and for this purpose I have provided a frame 23 carrying thecable guide-rollers 24-.

The current for actuating the motor 14 may be taken ofi from the supplycircuit to the locomotive in any desired way, and for illustration Thave simply indicated a conductor in leading from the said motor to theconductor which leads from the collector ring 18 to the motor or motors5 for drivin' the track-wheels.

The operation ofthe mechanism will be readily understood: Assuming thatthe locomotive is at a fixed point from which it is desired to use thecable reel, the free end of the cable 17 is electrically connected inany suitable manner tothe line circuit for the locomotive and current isthen supplied ,through the said cable to the driving motor or meters onthe car, and the locomoa friction brake to prevent the running away i ofthe reel and baclnlashing of the cable. TV hen the locomotive has movedas far away from the fixed point as desired, and is again ready toreturn toward the said point, the operator supply current to the motor14 andcause the rotation of its armature shaft i l in such direction asto wind up the cable 17 thereon-as locomotive moves toward the saidfixed point. The rate of rotation of the said reel relative to the rateof travel of the locomotive may be regulated and pro vided for in anysuitable manner. In case the reel should operate somewhat faster thandesired, will be noted that slippage may at their inner ends, areloosely throws the controller 16 so as to c.

and will occur between the elements of the friction clutch 12 and thuscompensate for the difference in travel of the locomptive relative tothe reel and thereby prevent undue stretching and straining of thecable.

. It will be noted that since the motor 14 for driving the cable reel isactuated entirely independently of the locomotive trackwheels, it may beoperated to effect the winding up of the cable upon the reelirrespective of which end of the locomotive the cable has been paid offfrom, and is therefore in advance as the locomotive returns toward thesaid fixed point where the cable is connected to the main conductor, andduring this travel of either end toward the said fixed point the cablewill be wound upon the reel. Again owing to the independence of drivefor the truck wheels and the reel and since the motor for driving thereel has its own separate controller, the speed of rotation of the reelrelative to the speed of travel of the locomotive may be varied at will.

It will be seen that the friction brake or retarding device act-sconstantly and with substantial uniformity upon the cable reel or drumso that the latter is held from overrunning under all circumstances, aswhen much or littleoof the cable is wound thereupon, and whether itsmotor is running or at rest. The supplemental motor for driving thereel, being independent of the motor that drives the track wheels, andunder the control of the operator, isalways in condition for instant useas occasion may require, being as eflicient for turning the reel whenthe last portion of a long cable is being wound thereupon as when theattached end is being wound, and vice versa.

While I have shown in the drawings a motor for actuating the cable reelwhich is separate and independent from the driving motors for thelocomotive track wheels, it will be understood that the self looking orautomatically locking feature of the train of power transmitting devicesfor driving the reel may be employed in connection with any rotary shafton the locomotive irrespective of how it is driven.

The controlling of the elements of a frie tion clutch in a train ofpower transmitting mechanism for driving a cable reel by means of a wormand worm wheel I believe to be solely novel to my apparatus.

The correlation of the worm, worm wheel and the elements of the frictionclutch is such that the friction elements of the clutch become retardingdevices when there is any tendency of the worm wheel to rotate in eitherdirection independently of the worm, the gears automatically locking toprevent such relative rotation, and compensation between the elements ofthe friction clutch and the reel being furnished by slippage of steadiedand it is prevented from unwinding the cable too rapidly. Such asteadying of the reel rotation is especially to be desired when thelocomotive is slowing up. When desired it is possible to energize thereel motor in the direction to tend to wind the reel with the resultthat the clutch element 12 is rotated in the opposite direction fromthat of the clutch element 12. In this manner the power of the motortends to oppose the unwinding movement of the reel. Obviously, when themotor is thus allowed to operate during the unwinding movement of thereel, it exerts a winding torque upon the winding device or reel; andwhen the operation of the motor is continuous, a winding torque isexerted upon the winding device during the movement of the vehicle ineither direction.

I do not herein claim any specific form of circuit connection orcontroller for the reel motor, many suitable forms, whether simpleswitches or current varying devices, being well known, but a device suchas that indicated is preferred.
